### <a name="Credential_Provider" />Protecting the Credentials with Credential Providers
In many Hadoop clusters, the core-site.xml file is world-readable. To protect
these credentials from prying eyes, it is recommended that you use the
credential provider framework to securely store them and access them through
configuration.
All ADLS credential properties can be protected by credential providers.
For additional reading on the credential provider API, see
[Credential Provider API](../hadoop-project-dist/hadoop-common/CredentialProviderAPI.html).
#### Provisioning
```
% hadoop credential create dfs.adls.oauth2.refresh.token -value 123
-provider localjceks://file/home/foo/adls.jceks
% hadoop credential create dfs.adls.oauth2.credential -value 123
-provider localjceks://file/home/foo/adls.jceks
```
#### Configuring core-site.xml or command line property
```
<property>
<name>hadoop.security.credential.provider.path</name>
<value>localjceks://file/home/foo/adls.jceks</value>
<description>Path to interrogate for protected credentials.</description>
</property>
```
#### Running DistCp
```
% hadoop distcp
[-D hadoop.security.credential.provider.path=localjceks://file/home/user/adls.jceks]
hdfs://<NameNode Hostname>:9001/user/foo/007020615
adl://<Account Name>.azuredatalakestore.net/testDir/
```
NOTE: You may optionally add the provider path property to the distcp command
line instead of added job specific configuration to a generic core-site.xml.
The square brackets above illustrate this capability.
